Abstract: A hand settable fuze interfaces with a servomotor to deploy a net from a projectile in flight. Prior to launch, a dial is rotated to both power on the fuze and set a preset delay. The projectile is then launched from a launcher system to deliver the stowed net rapidly and accurately toward a target. After the preset delay, the net is deployed from the projectile toward the target by operation of the servomotor.

Abstract: A safety device for a front-loading weapon of the type comprising a mortar barrel having a closed breech end and an opposite open end for launching a mortar projectile. The device includes at least one sensor, configured for mounting adjacent the mortar barrel, for sensing a mortar projectile upon its insertion in the barrel and an electronic circuit, coupled to said sensor, for detecting movement of the mortar projectile past said sensor, thereby to detect the presence of the projectile in the barrel.

Abstract: An electromechanical system translates an “aiming error” signal from a target tracking system into dynamic “pointing corrections” for handheld devices to drastically reduce pointing errors due to man-machine wobble without specific direction by the user. The active stabilization targeting correction system works by separating the “support” features of the handheld device from the “projectile launching” features, and controlling their respective motion by electromechanical mechanisms. When a target is visually acquired, the angular deflection (both horizontal windage and vertical elevation) and aiming errors due to man-machine wobble (both vertical and horizontal) from the target's location to the current point-of-aim can be quickly measured by the ballistic computer located internal to a target tracking device. These values are transmitted to calibrated encoded electromechanical actuators that position the isolated components to rapidly correct angular deflection to match the previous aiming error.

Abstract: A sight and methods of operation thereof are provided. In some embodiments, an image is captured via an image capture unit, and a center position is calculated according to the positions of at least three impact points in the image, and a predefined view center of a display unit is set to the center position. In some embodiments, an angle of dip of the sight to a plane is detected via a dip angle detector. A predictive impact point is calculated according to the angle of dip and at least one calculation parameter, and an impact point indication is accordingly displayed in the display unit. When the angle of dip is changed, the predictive impact point is recalculated according to the new angle of dip, and the corresponding impact point indication is displayed.

Abstract: A method is disclosed for providing an observer with an intuitive sense of the tactical situation in an operational area that surrounds a point-of-interest. The observer is simultaneously presented a top-down view of the operational area that includes contact indicators for each of one or more contacts within the operational area, and a status display that indicates the instantaneous hostility assessment of one or more of these contacts. In addition, the operator is automatically presented historical information, including contact images, for each contact whose hostility assessment exceeds a threshold level. The operator, or a group of operators, is enabled to view all of the displayed information from a single vantage point, assess the relative hostility of numerous contacts simultaneously, and rapidly confirm the identity of apparently hostile contacts prior to engagement.

Abstract: A method and apparatus for defending against airborne assault ammunition. The assault ammunition is located with at least one position-locating device. The flight path of the assault ammunition is iteratively calculated using the determined ballistic coefficient of the assault ammunition. A firing control solution is determined for firing a fragmentation-type defense ammunition, which is fired with a large-caliber weapon, especially one having a caliber of at least 76 mm. A fuse of the defense ammunition is set after the firing and/or the defense ammunition is remotely detonated, and after the firing the defense ammunition is ignited or remotely ignited at an ignition time point T. Alternatively, the ignition of the defense ammunition is initiated by a proximity igniter disposed in the defense ammunition.

Abstract: The determination of the active projectile velocity required for the correction computation and the correction of the disaggregation time (Tz(vo) are performed in a projectile after it has been fired. The velocity measurement takes place in the form of a measurement of a first time (t) which is required for a defined number of revolutions (Nm) of the projectile, wherein a velocity difference, which must be multiplied by a correction factor, is expressed by the actual projectile velocity and a lead velocity of the projectile by means of a time difference (t−tm) formed from the first time (t) and a predetermined second time (tm).

Abstract: The transmission of the disaggregation time takes place in the area of the conveying path of the projectiles (18) between a a magazine of the gun and the start of the flight path of the projectile (18), wherein the disaggregation time (Tz(Vo_typ)) is corrected by means of a delay time, which is a function of the selected transmitting point.

Abstract: It is possible to improve the hit probability of programmable projectiles by means of this method. For this purpose a predetermined optimal disaggregation distance (Dz) between a disaggregation point (Pz) of the projectile (18) and an impact point (Pf) on the target is maintained constant by the correction of the disaggregation time (Tz) of the projectile (18). The correction is performed by adding a correcting factor, which is multiplied by a velocity difference, to the disaggregation time (Tz). The velocity difference is formed from the difference between the actually measured projectile velocity and a lead velocity of the projectile, wherein the lead velocity is calculated from the average value of a number of previous successive projectile velocities.

Abstract: In this more cost-effective, less elaborate method, the disintegration time is calculated from a predetermined muzzle velocity and a distance to the target and is transmitted to a receiver coil prior to firing. The receiver coil is connected via a comparator circuit (7) and a decoder (8) with a shift register (9), whose output is connected to a first comparator (6), so that the disintegration time is present on the outputs of the latter. A first counter (1), which is connected with a clock generator (2) and a programmable counter (3), is unblocked or blocked by the start-stop pulses, supplied via the receiver coil, of a muzzle velocity measuring device. The programmable counter (3) forms a clock signal from the number of the clock pulses, added in the first counter (1) during the unblocked time, and of the clock generator frequency, whose frequency is equal to the muzzle velocity and is supplied via a is binary circuit (4) to a second counter (5).
